Basement Waterproofing in Scarborough, ON
Leaky or wet basement in Scarborough? TCR Pro waterproofs foundations and repairs cracks with a 20-year warranty. Free inspection & quote.
A leaking basement in a Scarborough bungalow usually starts small, a damp patch after a thaw or a white powdery line across the concrete blocks. Most of Scarborough was built in the postwar decades, and those block foundations have mortar joints that let water through once the soil outside stays saturated.
The area’s ravines and the land running toward the Bluffs also mean plenty of lots where water moves through the ground long after the rain has stopped. TCR Pro has been waterproofing and repairing foundations like these since 1998.
What basement waterproofing in Scarborough involves
Block foundations behave differently from poured concrete. Water enters through joints and the hollow cores of the blocks, so injecting a single crack rarely solves the problem. For these walls we typically build an interior drainage solution that collects water at the base of the wall and moves it out before it crosses the floor.
Where the lot allows it, exterior waterproofing is the more thorough option. We excavate along the affected wall, repair the masonry, apply a membrane and improve the drainage so the blocks stop sitting in wet soil.
In neighbourhoods like Agincourt, Guildwood and Birch Cliff we also see grading that has sunk toward the house over sixty years and downspouts that dump roof water right at the foundation. Sometimes correcting those details is part of the fix, and we will say so rather than sell you more than you need.
How the work proceeds
Every job starts with an inspection of the foundation, inside and out. We identify where the water enters, not just where it appears, because on block walls those can be metres apart.
Next comes a written quote with a defined scope and a firm price. Since we repair the existing foundation instead of replacing it, in most cases no permits or drawings are needed.
Our crew protects the areas we work in, completes the repair and leaves your basement and yard tidy. Basement waterproofing in Scarborough from TCR Pro is covered by a 20-year warranty.
Window wells deserve a mention on Scarborough bungalows, because they collect leaves and snowmelt until water sits against the frame. We check every well during the inspection, since a flooded well can imitate a failing wall.

Frequently asked questions
It depends on the size and type of damage, but repair almost always costs a fraction of a full replacement — no demolition, disposal or new pour. The fastest way to a price is to send us a few photos; we reply with an honest, free written quote.
The fastest route is to send photos of the damaged area through our contact form or by email. In many cases we can give a preliminary assessment from photos alone, and we arrange a site visit when the job needs one.
We are based in Mississauga and work across Toronto and the entire GTA, including Etobicoke, Brampton, Oakville, Burlington, Milton and surrounding communities. We also serve the Hamilton area, including Stoney Creek, Ancaster and Dundas, as well as Guelph, Caledon and Grimsby. If you are nearby but not on this list, ask us anyway.
Yes. Our work is backed by a written workmanship warranty. The warranty terms are provided in writing with your quote, so you know exactly what is covered before the job starts.
In most cases, yes. Cracks can be injected, spalled and pitted surfaces can be resurfaced, uneven slabs can be levelled and the whole surface can be protected with a durable coating. Repair usually costs a fraction of replacement and avoids demolition. When concrete is truly beyond saving, we tell you honestly before you spend anything.
Almost always, yes. Most cracks are repaired at full depth with injection or structural patching, which seals them against water permanently. Replacement is only needed when a slab has failed structurally through its whole thickness, which is rare.
Interior work such as basement floors, garage coatings, interior waterproofing and commercial floors continues year round. Exterior repairs and coatings depend on temperature and curing conditions, so outdoor work is scheduled around the weather. We can assess your project in any season and book exterior work for the right window.
In most cases, no. Repairing, resurfacing and coating existing concrete does not normally require drawings or permits, which is one of the reasons repair is faster and cheaper than replacement. Structural changes or full replacement can be a different story, and if your project touches that territory we will flag it before work begins.
Payment terms are stated clearly in your written quote before any work starts.
It depends on the size and the system, but most residential repairs are measured in days, not weeks. Coatings and overlays need curing time before the surface can take foot or vehicle traffic, and we tell you exactly how long to wait. Full replacement, by comparison, typically means demolition, forming, pouring and weeks of curing.
With a proper system and a protective sealer, quality resurfacing lasts for decades. Outdoors we use flexible, freeze-thaw and salt-resistant systems like Graniflex, and refreshing the sealer every few years extends the life further.
No. Our floor and deck coatings can be finished with slip-resistant additives or textures — we recommend them for pool decks, steps and garage floors so the surface stays safe when wet.
Yes. Alongside residential work we repair and coat commercial kitchen floors, warehouse floors, expansion joints, condo balconies and other commercial concrete. The repair-first approach matters even more commercially, because it keeps downtime short.
